Automatic painting process instructions

1. pre-coated primer:

1-1. Automatic painting equipment: the pieces, dust, preheating, dust, spraying, preheating, drying, the next pieces;

1-2. This product is a two-component system, the first slurry stirred, according to the proportion of adding curing agent, stir well aging 30 minutes.

1-3. With special thinner to adjust the construction viscosity; according to the amount of paint, with the number of how many with a good paint should be used within 8 hours.

1-4. Recommended a spray, viscosity 15-18 seconds (coated -4 #) dry film thickness of up to 25μm.

2. the primer construction:

2-1. Hardware products must be treated before spraying the substrate, requiring clean, no rust, no oil, keep clean and dry.

2-2. This product is a two-component system, the first slurry stirred, according to the proportion of adding curing agent, stir well aging 30 minutes.

2-3. With special thinner to adjust the construction viscosity; according to the amount of paint, with the number of how many with a good paint should be used within 8 hours.

2-4. Recommended spray 2, each dry film thickness of 35 ± 5μm, requiring construction interval of more than 20 minutes.

2-5. Such as grinding, the need to ambient temperature 15 ℃ above, dry 24 hours after.

3.the construction of unsaturated polyester putty

3-1. After the primer is completely dry, the construction of the putty can be carried out.

3-2. Open the lid, the first putty bucket stir, the proportion of curing agent added by adding evenly, you can scratch coating construction.

3-3. First scraping a 15 # putty, then scraping two 11 # putty, and then use three 15 # putty leveling.

3-4. Scraping every putty interval after 4 hours of grinding, and then scrape a putty, the last one to be carefully polished. If the winter temperature is too low, to extend the grinding time or by adding driers, adjust the curing time.

3-5. Putty is generally required to be used within 10-30 minutes, according to the construction needs can also be adjusted by adjusting the amount of curing agent for the time.

4. the construction of the primer:

4-1. Good scraping putty, polished smooth, you can spray primer coating.

4-2. Stir the slurry in the barrel, add the curing agent in proportion, add the curing agent, stir evenly, aging for 30 minutes.

4-3. According to the amount of paint, with the number with how much, with a good paint should be used within 8 hours.

4-4. With special thinner adjustment to the construction viscosity (about Tu -4 cup, 17-22 seconds) can be air spray.

4-5. Recommended spraying two, 24 hours in the interval, the second completely dry {ambient temperature above 15 ℃, 24 hours, according to the construction needs, with putty leveling defect, with sandpaper polished flat, and then spray the second primer.

4-6. Requirements in the coating film smooth, no sag.

5. the top coat of the construction:

1. Hardware painting requirements Dry substrate, no water, oil and other impurities.

2. Plastic spray paint requirements substrate dust-free, no water, no oil other impurities;

3. According to the amount of paint, with the number with how much, with a good paint should be used within 8 hours.

4. Zuo Neng technology to provide professional automatic painting equipment program, planning, design, manufacture, installation and service;

5. The use of supporting special thinner dilute, spray viscosity of about 17-23 seconds.

6. First spray a topcoat, make up the substrate defects, defect handling, and then spray the next one, each paint must be at ambient temperature above 15 ℃ dry 24 hours, then spray the next one.
